Mighty Pizza Oven heating time was about 30 minutes and took me about 20 minutes to prepare and bake 3 pizzas. Baking time was about 3.5 minutes. I don't know what the BTU for each can is, probably around 1,500 BTU each. I am still checking with the manufacturer to see if it is safe to use their product in this manner.

Here's YouTube link of the event, it is was bit windy, so I did the test in my garage. The large flames indicate the fuel has reached it's boiling point. Not sure if at boiling point the fuel gives higher or lower heat.

Simply, assume the weight of fuel in the can is 4oz (just a guess - I have no idea). It would contain 8730*(4/16) = 2183 BTU of energy (HHV*). The literature says the burn time is 5 hours = 437 BTU/hr.

*HHV = Higher Heat Value. One of the combustion by-products is water, and it takes heat to convert the water to water vapor. The net usable heat or LHV (Lower Heat Value) subtracts the heat of vaporization of the water produced. I don't know how meaningful it is in this case.

Did you happen to measure the temperature of the fuel cans after the MPO was at temperature?

Thanks Graig for make it simple to understand. The can weight is not listed on the can or their website. I will get it from the manufacturer or just weight it and guess amount used.
